Mobility Simulation for the Evaluation of UMTS Power Control Algorithms

Abstract

Mobility is a major feature in mobile networks. The aim of this study is to analyze its impact on the power control procedure in UMTS network through several power control mechanisms. Mobiles motion is simulated using the Mask Based Mobility Model, an emerging mobility model based on Markov chains. After presenting the power control procedure and algorithms in UMTS, a description of the simulation environment, scenarios and results will be given.
